4 Basic programming
Although solving a problem on an analog computer has basically the same prerequisites as programming a digital computer, the actual process of programming differs significantly from the now-predominant algorithmic approach. Figure 4.1 shows the main steps involved. First, the problem under investigation has to be examined and a mathematical representation, typically a system of coupled differential equations, DEQs for short, has to be derived. From here on the digital and analog ways of programming quickly diverge. On a digital computer these equations form the basis for an algorithm which will be executed in a stepwise fashion. When programming an analog computer the very same equations will be transformed into a patching ...
